'curl: no URL specified!' Installing Parity on AWS (Ubuntu)

Question

The accepted answer found here does not seem to work for me: https://ethereum.stackexchange.com/a/46926/11266

I created an EC2 instance of Ubuntu 16.04 LTS (HVM)

$ bash <(curl https://get.parity.io -Lk) -r stable
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   170    0   170    0     0   1465      0 --:--:-- --:--:-- --:--:--  1452
100  3847  100  3847    0     0  21491      0 --:--:-- --:--:-- --:--:-- 21491
Release selected is: stable
Upgrading parity from 0.0.0 to 1.11.10
curl: no URL specified!
curl: try 'curl --help' or 'curl --manual' for more information
/usr/bin/sha256sum: /tmp/tmp.NnKCndYjTQ/parity: No such file or directory
cp: cannot stat '/tmp/tmp.NnKCndYjTQ/parity': No such file or directory
rm: cannot remove '/tmp/tmp.NnKCndYjTQ/*': No such file or directory

I tried wrapping the url in quotes, but I'm getting the same result.

$ bash <(curl 'https://get.parity.io' -Lk) -r stable
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   170    0   170    0     0   1360      0 --:--:-- --:--:-- --:--:--  1349
100  3847  100  3847    0     0  21857      0 --:--:-- --:--:-- --:--:-- 21857

Answer 1

The problem is not with the one line command, but rather with the installer itself. You can see it by running:

 curl https://get.parity.io -Lk > installer.sh

to download the file and then by running

 ./installer.sh

You will get the exact same problem. The problem is related to the fact that the website from which it gets the URLs to download the binaries has changed the name for the stable and beta releases. So, you have to overwrite some variables in the bash file. From this

if [ "$RELEASE" = "beta" ]; then
    LOOKUP_URL="$VANITY_SERVICE_URL&os=$PKG&version=beta-release"
elif [ "$RELEASE" = "stable" ]; then
    LOOKUP_URL="$VANITY_SERVICE_URL&os=$PKG&version=stable-release"
else
    LOOKUP_URL="$VANITY_SERVICE_URL&os=$PKG&version=$RELEASE"
fi

To this:

if [ "$RELEASE" = "beta" ]; then
    LOOKUP_URL="$VANITY_SERVICE_URL&os=$PKG&version=beta"
elif [ "$RELEASE" = "stable" ]; then
    LOOKUP_URL="$VANITY_SERVICE_URL&os=$PKG&version=stable-backup"
else
    LOOKUP_URL="$VANITY_SERVICE_URL&os=$PKG&version=$RELEASE"
fi

Alternatively you can use

bash <(curl https://raw.githubusercontent.com/ethcore/scripts/master/install-deps.sh -L)

This will install and configure the Parity client for you.
